- Abstract
Background: This study examined the cross-sectional and longitudinal associations of cardiorespiratory fitness (CRF) and ideal cardiovascular health (CVH). Methods: CRF and the 7 CVH components were measured in 11,590 (8865 males; 2725 females) adults at baseline and in 2532 (2160 males; 372 females) adults with at least one follow-up examination from the Aerobics Center Longitudinal Study. Ideal CVH score was calculated as a composite of 7 measures, each scored 0 to 2. CVH groups were based on participant point score: ≤7 (poor), 8 to 11 (intermediate), and 12 to 14 (ideal). Analyses included general linear, logistic regression, and linear mixed models. Results: At baseline, participants in the high CRF category had 21% and 45% higher mean CVH scores than those in the moderate and poor CRF categories (P < .001). The adjusted odds (95% confidence interval) of being in the poor CVH group at baseline were 4.9 (4.4-5.4) and 16.9 (14.3-19.9) times greater for individuals with moderate and low CRF, respectively, compared with those with high CRF (P < .001). Longitudinal analysis found that for every 1-minute increase in treadmill time, CVH score increased by 0.23 units (P < .001) independent of age, sex, exam number, and exam year. Conclusions: Higher CRF is associated with better CVH profiles, and improving CRF over time is independently associated with greater improvements in CVH.
